Internal presentation slides sourced by Heise show that the Panther Point chipset, which drives Intel's Ivy Bridge processors, embeds a 4-port XHCI compatible USB 3.0 SuperSpeed controller. The controller sits aside two EHCI USB 2.0 controllers, and shares 4 ports over a USB hub. So, out of the 14 USB ports from the chipset, 4 will be SuperSpeed capable.
Panther Point is the codename of Intel's 7-series platform controller hub (PCH) chipset, which could carry the common market model names P77 and H77.
